Sewing machine device capable of automatically tensioning belt and facilitating belt replacement

Abstract

The invention relates to the technical field of clothing production, and discloses a sewing machine device capable of automatically tensioning a belt and facilitating belt replacement. The sewing machine device includes a protective shell, the inside of the protective shell is slidably connected with a driving wheel, and the top of the driving wheel is connected with a driven wheel in a transmission mode, the inside of the protective shell is slidably connected with a top rod, the top of a pulley is connected with a runner in a transmission mode, the inside of the runner is fixedly connected with a reel, and the top of the reel is movably connected with a pawl . According to the sewing machine device capable of automatically tensioning the belt and facilitating belt replacement, the top rod is pushed to move the left by a thrust spring, the top rod drives a slider to slide down, the slider presses water in a hydraulic box into a water pipe, the water pushes a piston to move to the left, the water pipe pours the water into an energized box, the water level in the energized box rises to energize an electrode block, a rotating shaft rotates, the rotating shaft descends under the action of a supporting plate, and the rotating shaft is used in conjunction with the driving wheel to achieve the effect of automatic adjustment of the belt tension degree.

Description

technical field [0001] The invention relates to the technical field of garment production, in particular to a sewing machine device capable of automatically tensioning a belt to facilitate belt replacement. Background technique [0002] In the process of clothing production and processing, the most commonly used equipment is the sewing machine. The sewing machine uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. In the early days of sewing machines, they were basically single-needle, hand-cranked sewing machines. Later, electric-driven sewing machines were invented and became the mainstream in the market. [0003] Most of the existing sewing machines use belts for transmission, and the belts tend to become loose during long-term use, which affects the use of the sewing machine. Only when there is a problem with the sewing machine, people will adjust the tightness, which not only da...
